Residue Number System Arithmetic Assisted Coded Frequency-Hopped OFDMA

open access: yesEURASIP Journal on Wireless Communications and Networking, 2009
We propose an RNS arithmetic-based FH pattern design approach that is well suited and easy to implement for practical OFDMA systems. The proposed FH scheme guarantees orthogonality among intracell users while randomizing the intercell interferences and ...

Quadratic residues and non-residues in arithmetic progression [PDF]

open access: yesJournal of Number Theory, 2013
Let S be an infinite set of non-empty, finite subsets of the nonnegative integers. If p is an odd prime, let c(p) denote the cardinality of the set {T {\in} S : T {\subseteq} {1,...,p-1} and T is a set of quadratic residues (respectively, non-residues) of p}.

Quantifying residual finiteness of arithmetic groups [PDF]

open access: yesCompositio Mathematica, 2012
Abstract The normal residual finiteness growth of a group quantifies how well approximated the group is by its finite quotients. We show that any S -arithmetic subgroup of a higher rank Chevalley group G has normal residual finiteness ...

Analysis of algorithms performing basic arithmetic operations in the quadratic RNS

open access: yesНаука. Инновации. Технологии, 2022
In this paper we explore the question of representing complex numbers in a residue number system and build algorithms for the operations of addition and multiplication. The idea of the construction of such systems is in determining how the set of complex

Fibonacci, tribonacci, …, hexanacci and parallel “error-free” machine arithmetic [PDF]

open access: yesКомпьютерная оптика, 2019
The paper proposes a new method of synthesis of machine arithmetic systems for “error-free” parallel computations. The difference of the proposed approach from calculations in traditional Residue Number Systems (RNS) for the direct sum of rings is the ...

A residue arithmetic implementation of the FFT

open access: yesJournal of Parallel and Distributed Computing, 1987
Abstract Recently, a new method of performing complex arithmetic in a residue arithmetic number system was reported. This paper extends these techniques into several application areas including the design of an FFT system. In addition, a new single-modulus complex residue number system (RNS) and sign management system is developed for use as a basic ...

Arithmetic Means for a Class of Functions and the Modified Bessel Functions of the First Kind

open access: yesMathematics, 2019
In the paper, by virtue of the residue theorem in the theory of complex functions, the authors establish several identities between arithmetic means for a class of functions and the modified Bessel functions of the first kind, present several identities ...
